3 Claims.

My invention relates to toilet seats and more particularly to an improved toilet seat of simple and novel construction having means to facilitate the excretion of waste matter from the human system and to save toilet paper.

Normally a person has to excrete the waste from his body twice daily and these operations cause more or less strain. This strain which is detrimental and unfavorable takes one form or another, for example separating the thighs and to separate the thighs and move or pull the buttocks apart without resort to self-strain which is detrimental and unfavorable to the body and stomach, or using the hands, thus facilitating the excretion. Practically always people dirty not the rectum but the surrounding area of the rectum when excreting fecal material. Therefore, the surroundings being stretched. by the present device are freed from contacting fecal material, thus saving in the excessive use of toilet aper. This device therefore is not only more sanitary, but also more economical.

Another object is to provide means on the side portions of the seat, including movable members forming intermediate or interposed sections of the sides of the seat, movable in and out and normally held in, and means for causing said members to move out by the weight of the body of a person using or reposed on the seat to'move the thighs and buttocks outwardly to separate or spread them and stretch the surrounding area of the rectum to facilitate excretion and prevent or free the said area from contacting fecal material, thus saving in the excessive use of toilet paper so that the device is not only more sanitary but also more economical.

Another object is to provide means on the side portions of the seat, including movable members forming intermediate or interposed sections of the sides of the seat, movable in and out and normally held in, together with means operable up and down or vertically by the weight of a person using the seat to move said members or sections outwardly to move the thighs and buttocks outwardly in opposite directions to separate or spread the thighs and buttocks and stretchthe surrounding parts for the purposes stated.

2. a With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed-out in the appended claims.

In the drawings, Figure 1 is a top plan of a toilet seat with the improvements of my invention embodied therein, Figures 2, 3 and 4 are. transverse or cross sectional views taken on the lines 2-'-2, 3-3 and 4-4 respectively of Figure 1, r 1

Figure 5 is a fragmentary section at right angles to Figure 2, taken on the line 5.5-of

.Figure 1,

Figure 6 is an enlarged fragmentary cross section taken on the line 6-6 of Figure 1 of a vertically movable seat section, Figure '7 is a side view of a laterally slidable seat section,

Figure 8 is a detailed elevation of a-pinion shaft, partly broken away and in section.-

Referring to the drawings, there is shown -a toilet seat It] which may be flat at the bottom and convex at the top tapering toward its opposite innerand outer edges or otherwise, and substantially the shape of an open ring or horseshoe and made of any suitable ring shape and durable material such as wood, plastic, metal or otherwise. Seat [0 has the straight or curved back bight or connecting portion H usually hinged to the bowl and outwardly curved or arouate sides l2 continued from portion 1 I and space apart at their front as at [3.

The sides l2 about midway of their lengths but slightly forwardly thereof at the outside, are provided entirely therethrough with horizontal transverse diagonal or inwardly and rearwardly slanting top slots, grooves or recesses l4 converging rearwardly and inwardly and diverging for,- wardly and outwardly having or leaving a horizontal bottom connecting wall 15 between the sides of the respective slots. The vertical front and rear walls of the slots M are provided lengthwise thereof with transverse parallel grooves 16 forming guideways for slidably receiving on rollers l6 conforming ribs or tracks I1 formed on and projecting from the opposed front and rear vertical faces of interposed horizontally sliding seat sections or plate members l8 convex at the outside or outer ends and concave at the inside or inner ends and in cross section to the sides l2 of seat In above the bottoms of the grooves l6. Sections I8 are hollowed out or recessed at the bottom andoutsides to form openings or chambers 19 with inner vertical walls 20 spaced, from the insides o said sections IR and inner seat ed es to leave connectin or wall portions 2| closing the recesses at their inner ends and freely open at their outer ends. The outer ends of slots l4 may be closed by arcuate cover plates or lids 22 a little lon er and dee er than the widths of the slides or slidable sections or members [8 and slots M to seat in seats. rabbets or recesses 23 in sections l8 and bottom walls l at the outside and secured in position in anv'su'itable way as by screws 24 disposed through holes in the late 22 and entering the walls of sections l8 at their outer en s or in other words, set in so as to be flush with the surfaces of the sides I 2 and sections 18. Plates 22 engage the sides 12 and l mit the inward movements of the seat sections I8.

At the underside of sections 18 or top walls :of recesses 19, sections I 8 are provided with rack teeth or bars 25 at least at the inner portions of the recesses, openingsor chambers I9 and ex- :tending len thwise of sections I8 parallel "to the "front and rear edges thereof medially therebe- "-tweenor otherwise and diagonally the same as "the slots I4 and sections 1R to which the rack teeth or'bars -25'a-re also parallel.

Spaced forwardly of slots I 4 sections 18 and parts therein, sides H are provided with transverse recesses or slots 26-divergent inwardly and conver entoutwardly-to slots H and sections [8 and extending partially acrosssides S2 at their upper or top portions only and shallower than slots M to receive vertically movable seat sections or plate members 2! conforming in cross section to the upper portions of sides I 2 as seen in "-F-igure 3. Sections '2! are provided medially with depending vertical toothed spindles or rack bars 28 which extend down through medial or central vertical passages 'or holes 29 in the horizontal wall portions 3!! of sides l2 below slots 26 and'sec'tions 21 and have their teeth set inward at an angle. Passages '29, circular or otherwise haveenlarged unper portions or seats 31 in which 'tl'ie lower-ends of expansible springs 32 restwhile their upper ends engage similar seats in sections '21 to normally elevate or raise-them in slots 26 above and in spaced relationto the bottoms thereof-andtop of seat H) at sides [2. Stops or screws 33 are secured in threaded horizontal holes in spindles or bars 28 near their lower ends to limit the upward movement of sections 21 and prevent them from coming out 'or being entirely displaced.

Sides I2 are hollowed out or recessed at the bottom as at 34 to receive the lower ends of spindles 28 and permit screws 33 to be mounted in position therein'or adjusted in'or out to form stops or limiting members as described, and recesses are closed at the bottom by cover plates 35 set in rabbets or recesses 36 in the bottom of sides 12 around recesses 35 and secured by suitable fastening means such as screws 31, to pro- :tect the interior parts from water etc., the same aswalls l5 and plates 22 protect parts in sections "8. Sections or plates '21 are also provided with means cooperative with the sides 2 at walls as to prevent turning or angling of said sections and spindles 2 8. Such means consist of depending logs or bosses 38 at the bottoms of sections 2'! at opposite sides of spindles 28' to enter correspondingly related holes or seats 39 in walls 351 shaped irregularly or otherwise as seen in Figure I, and to move up and down therein. Walls 48 are also formed between slots i4 and 26 at each side t2 of the seat In and horizontal tubular bearingsorholes 4 are provided through these walls 40- perpendicular to the slots M to rotatably re- 4 ceive shafts 42 having pinions 43 and 44 fixed on their ends in mesh with rack teeth of bars 25 and spindles or bars 28 respectively. To assemble the device, shafts 42 are inserted in bearings or holes 4| and are each provided with holes 45 and 4 5 to receive cotter or other pins 41' to hold it in place after insertion in the bearings or holes with sections l8 and 21 out of slots or recesses I4 and 26 or before insertion therein. Pinions 43 and M are then attached or fixed to the ends of the "shafts 42, as by screws, threads or otherwise, in position to engage rack teeth 25 and 28. Sections i8 are then inserted or slid into position in their sguideways in their inwardly projected positions as seen in Figure 1 with teeth 25 engaging pinions 13. Sections 21 are then dropped into position withscrews'33 removed and springs 32 on spindles or rack bars 28 and the latter inserted in holes 29, after which screws 33 are turned into position so as to project, or they may be seated in cavities or counterbores around the threaded holes or ss'ockets in spindIesZB which receive them topass through holes 29 and then turned out to act as stops or limiting members or means for the upward movements of the sections 21 under the action of 'the'raising springs 32. Sections 21 are thus normally elevated, raised, pushed or ,pro- :jected upwardly by the springs above the 'levelof the top faces of sides i2-of :seat 10. 'Thus, when the weight of a person reposed on the seat is placed on the laterally movable sections 18 and :plungers or vertically movable sections 21, the

latter will move downwardly to cause the teeth of the rack bars or spindles 28 to engage the teeth of the pinions 44 and rotate shafts 42 in op- 'posite directions at opposite sides of the seat and by rotating the pinions 43 in mesh with the teeth of the rack bars 25, cause the movable sections [8 to slide outwardly and owing to the friction of 'thetparts of the person therewith cause the thighs :and buttocks to move outwardly to separate or spread 'themras well as to stretch the surrounding area :of the rectum, thus facilitating excretion, and preventing or freeing said area from contact with the fecal material, 'thus saving in the excessive use of toilet paper so'that'th'e device is not only more sanitary, but also more economical. The top surfaces of the sections 18 and 21 may was-shown at '48 be formed or covered to insure proper friction between the same and the parts pithe erson resting "thereon and cause the separation or spreading and stretching above re- :ferred to for the purpose stated.

I donot mean to confine myself to the exact details of construction herein disclosed but claim all variations falling within the purview of the appended claims.

What I claim is:

1. A toilet seat including spaced apart sides, horizontally movable seating portions in said sides adapted to move in and out with respect to said sides, a vertically movable actuating portion mounted on each of said sides, resilient means interposed between each of said actuating portions and the related'side for constantly urging said actuating portion upwardly, and geared driving means operatively connecting said actuating portiohs to said horizontally movable portions and adapted to move said latter portions outwardly when said actuating portions are depressed by the weight of a person positioned on the seat.

2 A toilet seat having side portions horizon tally slidable seatingpsections mounted in said side portions, vertically movable actuating pore tions carried by said side portions and disposed on top thereof, resilient means adapted to constantly urge said actuating portions upwardly, and geared operating means operatively connecting said actuating portions to said slidable sections and adapted to move said sections outwardly when said actuating portions are depressed whereby the weight of a person positioned on the seat will efiect the outward movement of said sections to spread and separate the thighs and buttocks of the person and stretch the area surrounding the rectum.

3. A toilet seat having side portions, horizontally slidable seating sections mounted in said side portions, a horizontally disposed gear rack fixedly carried by each of said sections, vertically slidable actuating portions disposed above said side portions and carried thereby, a vertically disposed gear rack carried by each of said actuating horizontally disposed gear racks and adapted to move said sections outwardly whensaid actuating portions are depressed, and spring means interposed between said actuating portions and said side portions for constantly urging said actuating portions upwardly whereby the weight of a person positioned on said seat will effect the outward motion of said sections to separate the thighs and buttocks of the person.
